Title: Method and device for controlling resistance welding machine
Inventor: FUJII KOJI
IPC: B23K11/24
Filed: 1990-02-20
Abstract: PURPOSE:To always warrant the quality of a weld zone by calculating the diameter of an isothermal line from a detected surface temperature distribution of materials to be welded, comparing the diameter with the reference diameter, controlling a welding current according to the difference between the diameters and stopping the welding current when the diameter of the isothermal line is coincident with a maximum value of the reference diameter. CONSTITUTION:The surface temperature distribution of the material 2a to be welded corresponding to the peripheral parts of welding electrodes 1a and 1b is detected by an optical image fiber 4 and a temperature detector 5. The diameter of the isothermal line is detected from the surface temperature distribution. The diameter is compared with the reference diameter predetermined corresponding to extension of the nugget diameter. A welding current value applied to the welding electrodes 1a and 1b is controlled according to the difference between the diameters and the diameter of the isothermal line is allowed to follow up the reference diameter. When the diameter of the isothermal line is coincident with the maximum value of the reference diameter, the welding current applied to the materials 2a and 2b from the welding electrodes 1a and 1b is stopped. Consequently, safety, working efficiency and economy can be improved.

Filed: 1994-03-10
Abstract: PURPOSE:To feed film at a constant speed at least in the period when an image is read by a line sensor in the case of intermittently reading a film image from developed photographic film by one frame. CONSTITUTION:The developed photographic film 30 is moved at the constant speed, set at a position (standby position) where the film 30 is stopped by every frame in the case where the film image of one frame is read from the film 30 by using the line sensor, and positioned so that a run-up distance d1 where the constant speed is attained from the standby position to a picture reading start position may be obtained.

Filed: 1999-02-19
Abstract: PROBLEM TO BE SOLVED: To install an antenna matching a desired satellite reception even when there is another satellite in proximity, concerning the angle and direction of the satellite reception. SOLUTION: In this low noise block down converter, a signal branched by a second branching device 17 has a proper gain secured by a third IF amplifier 18, then is frequency-limited by a second band pass filter 19 picking up only a specific frequency band, passes through a second rectifying filtering circuit 20 outputting a signal including a lot of DC components obtained by rectifying and filtering an AC signal, and then is inputted to a first comparator 21. Then, the presence/absence of the signal is judged by a specific threshold value in the comparator 21, and the judging result is outputted to a second display lamp 22. For example, a signal from a satellite, where the passing frequency band of the filter 19 is a unused channel, is judged to be absent by the comparator 21, and a signal from a satellite, where the band is an in-use channel, is judged to be present.
